چکیده

به منظور بررسی تنوع ژنتیکی و تجزیه ارتباط برای صفات مورفوفنولوژیک و مقاومت به بیماری سفیدک پودری در ژرم‌پلاسم گندم با استفاده از نشانگرهای ISSR، IPBS و IRAP ، 115 ژنوتیپ گندم در سال زراعی 94-1393 در مزرعه تحقیقاتی دانشگاه گنبد کاووس در قالب طرح بلوک‌های کامل تصادفی با سه تکرار انجام شد. ژنوتیپ‌ها از تنوع بالایی برخوردار بوده و بین ژنوتیپ‌ها تفاوت معنی‌داری از لحاظ کلیه صفات مورد ارزیابی بجز طول دانه وجود داشت. به‌منظور ارزیابی تنوع مولکولی در 60 ژنوتیپ گندم، تکثیر از 8 آغازگر ISSR، IPBS و IRAP استفاده شد. از 61 باند تشکیل شده 47 باند چند شکل بودند. تعداد باندهای چند شکل از 2 تا 14 به ازای هر آغازگر متفاوت بود. بیشترین و کمترین درصد چندشکلی مربوط به آغازگر نوع ISSR و iPBS به ترتیب با 100 و 50 درصد بود. همچنین در این بررسی واکنش 60 ژنوتیپ و لاین گندم در برابر قارچ عامل بیماری در شرایط درون شیشه‎ای مورد ارزیابی قرار گرفتند. تجزیه خوشه‎ای لاین‎ها را در سه گروه حساس، مقاوم و حدواسط قرار داد. بر اساس نتایج مقایسه میانگین به روش LSD، لاین‌های 127 و 801 مقاوم‎‎ترین لاین‎ها بودند در حالی که لاین‎‎های 390، 515 و 833 بیشترین حساسیت را نسبت به بیماری نشان دادند. تجزیه ارتباط بین نشانگرها و صفات نشان داد که 56 آلل با صفات در ارتباط هستند و آلل PR50-6 بیشترین ارتباط را با صفات مورد ارزیابی داشت. با استفاده از نتایج این پژوهش ژنوتیپ‌های برتر می‏توانند برای مراحل بعدی به‎نژادی گزینش شوند.

چکیده [English]

In order to evaluation of genetic diversity and association analysis of morpho-phonological traits and mildew disease of wheat germplasm, 115 wheat genotypes were planted in the research field of Gonbad Kavous University as RCBD design with 3 replications in 2015-16. According to the results, there was a significant difference between all measured traits except grain length. In order to evaluation of molecular diversity in 60 wheat genotypes, 8 ISSR, IPBS and IRAP primers were used. Out of 61 bands produced in total, 47 bands were polymorph. The number of polymorphic bands was different range from 2 to 14 bands for each primer. The maximum percent of polymorphism with %100 polymorphism belonged to PRI-46 primer, and the minimum percent of polymorphism with %50 polymorphism belonged to PRI-59, PRI -10 and PRI-5 primers. In this study, also 60 genotypes and lines of wheat were evaluated in-vitro against Bgt. Cluster analysis of data of Powdery mildew caused was grouped lines in three groups of sensitive, resistance and median using UPGMA algorithm and Euclidian distance. Mean comparison using LSD indicated that lines 127 and 801 were high resistance but lines 390, 515 and 833 were susceptible to Bgt. Association analysis between markers and traits morpho-phenological showed that a total of 56 alleles showed a connection between the characters and PR50-6 allele associated most relevant to the characters. Based on results of this research, the higher genotypes could be screened for advanced wheat breeding steps.
